実験手順
To a suspension of (1S,3R)-3-(6-tosyl-6H-pyrrolo[2,3-e][1,2,4]triazolo[4,3-a]pyrazin-1-yl)cyclopentanamine hydrochloride (0.05 g, 0.11 mmol, prepared using E from Preparation #B.1 and HCl) and TEA (0.03 mL, 0.21 mmol) in DCM (5 mL) at about 0° C. was added 3-chloropropane-1-sulfonyl chloride (0.02 g, 0.11 mmol) dropwise. The reaction mixture was stirred at about 0° C. for about 1.5 h. The reaction mixture was diluted with 5% aqueous citric acid (10 mL), and the layers were separated. The organic layer was washed with saturated aqueous NaHCO3 (10 mL), water (10 mL), brine (10 mL), dried over anhydrous MgSO4, filtered, and concd under reduced pressure to give 3-chloro-N-((1S,3R)-3-(6-tosyl-6H-pyrrolo[2,3-e][1,2,4]triazolo[4,3-a]pyrazin-1-yl)cyclopentyl)propane-1-sulfonamide (0.052 g, 91%) as a brown residue: LC/MS (Table 1, Method a) Rt=2.18 min; MS m/z: 537 (M+H)+.
